elizabeth. maybe not NI-43-101 certified) of 558 million tonnes who has one.43 billion kilograms away from copper, million g of silver and you can 140 billion kilograms off molybdenum out of the fresh new leached cap, supergene (oxide and you can sulphide) and you can hypogene zones. One of them computation is actually an extended high-grade open pit mineable core of 90 million tonnes leveling 0.4% copper, 0.05% molybdenum and you will 0.forty eight g/t silver. (Yukon Mining and you can Geology 1993, p. four and you can Pacific Sentinel Silver Corp. 1993 Annual Declaration p. 4).

The fresh new leached cap/oxide silver area (making use of their a good 0.forty g/t silver cutoff) already machines an additional thirty two mil tonnes off shared measured and you will conveyed information.
